Parameters

Description

If bool is TRUE, the notimeout() function disables a timer used by
getch(3XCURSES) when handling multibyte function key sequences.

When bool is FALSE and keypad handling is enabled, a timer is
set by getch() to handle bytes received that could be the
beginning of a function key (for example, ESC). If the remainder of
the sequence is not received before the time expires, the first byte
is returned; otherwise, the value of the function key is returned. Subsequent
calls to the getch() function will return the other bytes received for
the incomplete key sequence.

The timeout() and wtimeout() functions set the length of time getch()
waits for input for windows stdscr and win, respectively. These
functions are similar to nodelay(3XCURSES) except the time to block or
wait for input can be specified.

A negative delay causes the program to wait indefinitely for input; a
delay of 0 returns ERR if no input is ready; and
a positive delay blocks until input arrives or the time specified expires,
(in which case, ERR is returned).
